water and waste tanks for boats
the best in fabricated plastic tanks
what we make
We at Goodwin Plastics are now in our 25th year of manufacturing and what a journey we have travelled. From pig farming to the establishing of a large plastics company and then on to the design, manufacture and distribution of bespoke products for all types of industry including agriculture, sports and leisure, and emergency services. We now ship our products to several different countries.
But one of our main businesses is the manufacture of water and waste tanks for canal boats and yachts.
why make tanks out of plastic?
We have come a long way in our manufacture of plastics, until we are now creating the best fabricated plastics on the market.
When creating water tanks, plastic is the perfect material. It can take any shape or size, is extremely tough and can be made right here at Goodwin Plastics in Crewe.
We make plastic water tanks to meet all specifications.
Polypropylene tanks are very easy to clean, light weight and don’t harbour bacteria - while stainless steel tanks can be very heavy, and do have a tendency to rust at the welded joint.
why are our tanks baffled?
All tanks are fully Internally baffled to help reduce the movement of the liquid which otherwise could cause stress on the tank sides.
Inside the water tanks the baffles are from top to base with areas cut out to allow the passing of water and for the air to escape.
On our waste holding tanks the welding of the tank is the same as that of the water tanks, but the design of the internal baffle is different.
The baffles inside the waste tank are shaped more like a bridge so there is no obstruction for the waste to get behind and build up.
reliable and durable plastic fittings
Our aim is always to make exactly what you need and to use the best possible materials to do it. That’s why we use plastic such as Perspex and polycarbonate sheeting along with other styles of plastic fabrication. That way, whatever we make is a strong as possible, durable and long lasting and needs only basic maintenance.
choosing the right tank
Sometimes you know you need a tank but aren’t quite sure of the specifications or dimensions. We are happy to help with this by assisting you to work out the size of the tank you need before designing it. All of the tanks we make also come with a standard BSP threaded sockets that are welded into the tank as well as hose tails supplied to screw into position.
All tanks are fabricated with Polypropylene which is a tough and durable plastic that has a high impact strength.
We can provide tanks for any purpose across the country and also offer a range of other plastic fabrications for professional or personal use.
working out the volume
To work out the volume of the tank that you require, there is a calculation as below:
e.g. Fresh water tank 48″ x 24″ x 24″ :
48 x 24 x 24 = 27648 cubic Inches. Divide this by 1728. This will give you the cubic feet volume (16). Multiply this figure by 6.25, this will give you the volume of the tank in gallons (100), multiply this figure by 4.54 for litres (454)
The volume of this tank 48″ x 24″ x 24″ is 100 gallon or 454 litres.
Full range of water tanks
We offer a range of water tanks suitable for boats, campers and other mobile homes.
These include water tanks with a pump available in different sizes to ensure you have a steady supply of fresh water. We also offer polypropylene water tanks that can sit under the hull or bow floor of a boat and meet the latest RINA and AISR standards.
Other tank variations include flare edged polypropylene tanks complete with inspection cover, tri water tanks and also wall hanging water tanks. The last of these is ideal for mounting behind cabinets or interspaces and have a level indicator flange.
We specialize in creating water and fuel tanks made to standard or custom specifications. We work in a range of plastic materials including polycarbonate and Perspex.
We can create what you need from scratch if we don’t already have it. Call us today for an initial no-obligation quote for any plastic fabrication needs.
